I'm going to be replacing the Colts on my RAN F-8E & RAM SLUF's with 30mm ADEN cannon ... we did it to the F-86F

Mind, the SLUFs do use the M-61 Vulcan, not the 20mm Colts, so the interior space, etc., may not lend itself to changing over to the Adens. Not sure why you'd want to if you have the Vulcan in place. It's a lot better gun than the 20mm Colt.

The Vulcan is not as fast reacting, nor is it as accurate and finally, it isn't as hard hitting as the ADEN/DEFA guns. The Vulcan has to be "spun up" before it can fire, whereas the revolver cannons are ready to fire as soon as they loaded and cocked. I have to laugh at the fan-boy slavish praise of the GAU-8. Yes, it's a hard hitting gun but not as hard hitting or as accurate as either the revolver cannons or the Oelikon all of which were trialed against it but rejected because of "not invented here".

And the old ADEN / DEFA 30mm is pretty sad compared to more modern 30mm offering and even the 25mm NATO, which was meant to be offered in a rechambered ADEN on the Sea Harrier FRS 2 (F?A-2) and GR5/7/9. The Tiger helicopter uses the old ADEN 30mm case and it is noticeable smaller than the 25mm used by the Army and Navy.

From the Retromechanix article I linked to:

I stand corrected (somehow I missed that figure altogether when reading the article... ). Apparently the flight envelope could be radically changed by changes in aerodynamics while still keeping the same basic form. Should have noticed from the decrease in top speed that something major was going on...
